DESCRIPTION

[0004] The present invention relates in general to a beverage dispensingapparatus, and in particular to a beverage dispensing apparatus for aresidential refrigerator which produces and dispenses carbonated andnon-carbonated beverages from a plurality of drink supply canisters.

BACKGROUND OF THE INVENTION

[0005] Many households in the United States and throughout the worldconsume large volumes of beverages such as soft drinks, sodas, juices,lemonade, teas, isotonics, fruit drinks and other beverages on a dailybasis. For instance, in 1998 retail sales of soft drinks in the UnitedStates were approximately 54 billion dollars, retail sales of fruitdrinks in the United States were approximately 17.5 billion dollars andretail sales of isotonics in the United States were approximately 2.25billion dollars.

[0006] Manufacturers in the beverage industry produce packaged beveragesfor consumers in the form of bottles, cans and cartons. They alsoproduce liquid and powder beverage concentrates which require consumerpreparation. Preparing beverages from concentrate by hand can beburdensome, time consuming and monotonous. Producing carbonatedbeverages from concentrate in homes using know commercial equipment isimpractical because special equipment and supplies are required. Suchhome mixed beverages are often of inconsistent quality and flavor.

[0007] For those who choose not to prepare beverages from concentrates,maintaining an adequate supply of packaged ready-to-drink beverages canbe relatively burdensome for families which experience a largeconsumption of beverages. Beverage containers, consisting largely ofwater, are somewhat heavy, and such beverage containers occupysubstantial space in refrigerators. In many families, at least once perweek, family members stock their refrigerators with packaged beveragesbecause of limited refrigerator space. The amount of availablerefrigerator space limits a family's supply of refrigeratedready-to-drink beverages.

[0008] One way of minimizing a family's beverage supply tasks is byusing a refrigerator which produces and dispenses ready-to-drinkbeverages. A number of beverage dispensing devices have been proposedspecifically for household refrigerators, some of which involveproducing carbonated beverages. The most common device enables consumersto dispense water and ice from a dispenser built into the exterior of arefrigerator door. Such types of dispensers are disclosed in U.S. Pat.Nos. 5,956,967 and 6,039,219. Other dispensers enable consumers todispense ready-to-drink beverages. Certain of these devices involve aconnection between a beverage container in the refrigerator and a spoutattached to the outside of the refrigerator. Pumping and otherapproaches have also been suggested to move the ready-to-drink beveragefrom the container through the spout. Devices such as these aredisclosed in U.S. Pat. Nos. 5,791,523, 5,791,517, 5,542,265 and4,930,666.

[0009] One refrigerator dispenser, disclosed in U.S. Pat. No. 3,949,903,involves the mixing of syrup and water and the dispensing ofnon-carbonated beverages. Another refrigerator dispenser disclosed inU.S. Reissue Pat. No. Re. 32,179 involves the mixing of syrup andcarbonated water and the dispensing of carbonated beverages.

[0010] One problem with these refrigerator dispensers is the need toclean them. Since the refrigerator dispensers house and distributeconsumable beverages, the dispenser components which come into contactwith fluids must be cleaned to avoid bacteria growth and othercontamination. The existing refrigerator dispensers include a relativelyhigh number of separate components which require regular cleansing toprevent contamination. Furthermore, many of the components are notremovable, and many are difficult to fully clean. Therefore, it isinconvenient and in many cases not possible to fully clean thecomponents of the currently known refrigerator dispensers withoutdisassembling these dispensers.

[0011] Although known refrigerator devices may enable users to dispensecarbonated and non-carbonated beverages from residential refrigerators,the construction of these devices is relatively complex, and the use,supply and maintenance of these devices is relatively inconvenient,cumbersome, time consuming and generally impractical. Additionally, suchknow devices do not solve problems such as cross-contamination ofdifferent beverages. Thus, while the patents indicated above disclosebeverage dispensing mechanisms, there is no known commercially availablerefrigerator system for dispensing ready-to-drink beverages whicheliminate cross-contamination problems.

[0012] Dispensing machines in commercial establishments are also wellknown for producing concentrate-based beverages. These machines, oftenfound in restaurants and eateries, typically involve the mixing of syrupand carbonated or non-carbonated water and the dispensing of beverages,such as soda. Commercial machines such as these are disclosed in U.S.Pat. Nos. 5,647,512, 5,392,960 and 4,993,604. However, such commercialmachines have not been suitably adapted for residential or home use oruse in conjunction with residential refrigerators.

[0013] Countertop units for dispensing beverages have also beendeveloped. For instance, Bev Star, Inc. produces a three drinkcountertop dispenser. However, such countertop units take up substantialadditional counter space which is highly undesirable in most households.These devices also only dispense a limited number of drinks. Suchcountertop units may have valve brixing problems, mechanical failuresand general reliability issues. Countertop units also utilize mechanicalrefrigeration to chill the water, which adds tremendous costs to thepotential home consumer, thus adding to the impracticability of theapplication for the home user.

[0014] Accordingly, the assignee of the present invention owns U.S.patent application Ser. No. 09/589,725 entitled “Beverage Distributionand Dispensing System and Method” which discloses and claims a beveragedistribution and dispensing system which enables users to dispense aplurality of beverages from a residential refrigerator, which tracksbeverage consumption and the use of the drink supply and CO₂ supply,which automatically orders drink supply and CO₂ supply as necessary,which facilitates the delivery of drink supply and CO₂ supply to theusers, which enables the users to determine beverage consumption and tochange the dispensed beverages, and which reduces the need to storeconventional beverage containers in the refrigerators of the users.

[0015] The present invention provides an improved beverage dispensingapparatus which is adapted to be used in conjunction with the beveragedistribution system disclosed in that U.S. patent application.

SUMMARY OF THE INVENTION

[0016] The beverage dispensing apparatus of the present invention ispreferably housed within a residential refrigerator to enable consumersto practically, conveniently and reliably produce and dispensenon-carbonated and carbonated beverages from their refrigerators. Thedispensing apparatus also facilitates the commercial availability andstandardized manufacture and distribution of drink supply canisters andCO₂ gas supply canisters for residential refrigerators.

[0017] For purposes of this application, the term: (a) “user” or “users”includes users of the beverage dispensing apparatus of the presentinvention such as users, consumers, household members and otheroperators of the apparatus; (b) “beverage dispensing apparatus” isalternatively referred to as “dispensing apparatus” or “beveragedispenser”; (c) “beverage” includes any ready-to-drink liquid; and (d)“drink supply” includes any liquid, which in and of itself, is aready-to-drink liquid or any liquid or non-liquid which requires theaddition of carbonated or non-carbonated water or other fluid(s) inorder to become a ready-to-drink beverage including, but not limited to,any syrup or concentrate which consists of predetermined percentages ofwater and flavoring or sugar.

[0018] Generally, one embodiment of the beverage dispensing apparatus ofthe present invention includes: (a) a drink supplier including a drinksupply canister holder for holding or maintaining at least one andpreferably a plurality of drink supply canisters, and at least one andpreferably a plurality of valve actuators for causing the drink supplyto be selectively released from the drink supply canisters; (b) a watersupplier for selectively supplying carbonated water and non-carbonatedwater for producing the beverages; (c) a gas supplier for supplying CO₂gas to carbonate the carbonated water provided by the water supplier,and in one embodiment, for supplying CO₂ gas or other gas forpressurizing the drink supply canisters to provide a consistent flowrate of the drink supply from the drink supply canisters; (d) a beveragecontainer compartment for holding a beverage collector or container suchas a glass, cup or pitcher; (e) in one embodiment, a fluid director forfacilitating the mixing of the drink supply from one of the drink supplycanisters and the carbonated or non-carbonated water from the watersupplier and for directing the mixed beverage to the beverage containercompartment; (f) a controller or dispensing computer or processor forcontrolling and tracking the dispensing of drink supply and carbonatedor non-carbonated water; and (g) one or more suitable beveragerequesters (such as indicators, actuators, buttons, a touch panel or atouch screen) for enabling users to request one of a plurality ofbeverages.

[0019] In one alternative embodiment of the present invention, the gassupplier includes an air pressurizer or pressurization device forpressurizing the drink supply canisters to reduce the volume of CO₂ gasused by the dispensing apparatus.

[0020] In one preferred alternative embodiment, the drink supply andcarbonated or non-carbonated water is directed directly to a beveragecontainer in the beverage container compartment (i.e., without a fluiddirector) to eliminate any potential cross-contamination and the need toregularly clean the fluid director. These and other alternativeembodiments of the present invention are discussed in more detail below.

[0021] Generally, in operation, after the user installs the drink supplycanisters, the CO₂ gas or other pressurized gas from the gas supplierpressurizes the drink supply canisters. When a user desires to obtain abeverage, the user makes the user's request through the beveragerequester which is preferably connected to or in communication with thedispensing computer or controller. The controller determines the user'srequest and generates a beverage dispense signal. Upon receiving abeverage dispense signal from the controller, the appropriate drinksupply outlet valve actuator associated with the appropriate drinksupply outlet valve in the appropriate drink supply canister opens for apredetermined period of time to dispense the appropriate amount of drinksupply from the drink supply canister. This drink supply is directedinto one of the channels of the fluid director (or in the alternativeembodiment directly into the beverage container). Simultaneously, uponreceiving a beverage request signal from the controller, the watersupplier directs the appropriate amount of carbonated or non-carbonatedwater into the same channel of the fluid director (or in the alternativeembodiment directly into the same beverage container). The drink and thecarbonated or non-carbonated water mix in that channel of the fluiddirector (or in the alternative embodiment, mix as both the drink supplyand carbonated or non-carbonated water are directed into the beveragecontainer), and the fluid director directs the mixed drink supply andthe carbonated or non-carbonated water (i.e., the beverage) to thebeverage container compartment.

[0022] The drink supply canister holder is preferably built into orconstructed within the freezer compartment door or refrigeratorcompartment door, and includes drink supply canister slots or areas forreceiving and holding the plurality of drink supply canisters. The drinksupply canister holder enables users to remove used drink supplycanisters and insert new drink supply canisters into the drink supplycanister holder.

[0023] In one preferred embodiment of the present invention, the drinksupply canister is a pressurizable encasement which has a gas inletvalve and a drink supply outlet valve. One embodiment of the gas inletvalve is a spring activated valve which is predisposed to be normallyclosed to prevent the flow of gas into or out of the drink supplycanister. When the gas inlet valve is depressed or activated, gas suchas CO₂ or pressurized air is communicated through the gas inlet valveinto the drink supply canister. One embodiment of the drink supplyoutlet valve includes a sealing member which is positioned in the bottomwall or end of the canister such that the sealing member can be tiltedor displaced horizontally. The drink supply outlet valve maintains aseal on the inside of the canister when the drink supply canister ispressurized. When the sealing member is displaced, the sealing memberunseats, and the drink supply outlet valve opens and causes pressurizeddrink supply to flow from the drink supply canister. One or more valveactuators are mounted to or adjacent to the drink supply canisterholder. When a user activates a beverage requester, a controller causesone of the valve actuators to engage and displace the sealing member ofthe drink supply outlet valve for a predetermined amount of time, whichin turn causes drink supply to flow from the drink supply canister.After a predetermined time period elapses, the valve actuator disengagesthe sealing member, stopping the flow of drink supply from the drinksupply canister. It should be appreciated that the present inventioncontemplates alternative suitable gas inlet valves, drink supply outletvalves and drink supply outlet valve actuators as discussed below.

[0024] The water supplier of the present invention provides carbonatedand non-carbonated water to the fluid director or directly to thebeverage container in the beverage container compartment for mixing thebeverages. The water supplier is connected to a drinkable water source,such as a conventional cold water source commonly available inresidential kitchens. One embodiment of the water supplier includes aholding tank which stores a sufficient supply of water. The water supplyfrom the holding tank is used if a user requests the dispensingapparatus to dispense non-carbonated water alone or if the dispensingapparatus requires substantial amounts of non-carbonated water. Thewater supplier also includes a carbonation tank connected to the gassupplier. The carbonation tank uses CO₂ gas obtained from the CO₂ gassupply canister and particularly the gas supplier to carbonate thewater.

[0025] In one embodiment, a carbonated water supply line and anon-carbonated water supply line are each separately mounted above thefluid director or directly above the beverage container compartment. Inone embodiment, the water supplier includes a plurality of carbonatedwater valves and non-carbonated water valves. The carbonated watervalves are connected to the carbonated water line, and thenon-carbonated water valves are connected to the non-carbonated waterline. A water valve actuator is mounted adjacent to and connected toeach carbonated water valve and each non-carbonated water valve. When auser activates a beverage requester, the controller causes a water valveactuator to engage and open a carbonated water valve or a non-carbonatedwater valve located above a particular channel of the fluid director ordirectly above the beverage container compartment. The actuatormaintains the valve open for a predetermined amount of time. After suchtime elapses, the water valve actuator allows the valve to close. Inanother embodiment illustrated, the carbonated water line is connectedto a single multi-way carbonated water valve, and the non-carbonatedwater line is connected to a single multi-way non-carbonated watervalve. When a user activates a beverage requester, the water valveactuator causes a multi-way valve to open and direct water to one of aplurality of channels for a predetermined period of time.

[0026] It should be appreciated that the drink supply outlet valveactuators and the water valve actuators can be constructed such thatboth cause the respective valves to open for the time period duringwhich the beverage requestor is activated by the user. In such case, theexact amount of drink supply and carbonated and/or non-carbonated waterare dispensed simultaneously to form the beverage.

[0027] One preferred embodiment of the present invention includes aplurality of water dispensers connected to the carbonated andnon-carbonated water lines. The water dispensers are disposed between orconnected to each pair of carbonated water valves and non-carbonatedwater valves over each channel entrance of the fluid director or overthe predetermined location or slot for each beverage container in theembodiments without the fluid director. Depending on the request by theuser and the type of beverages dispensed, either the non-carbonatedwater valve or the carbonated water valve will open and allownon-carbonated water or carbonated water to flow into the waterdispenser. The water dispenser diffuses and directs the water into theappropriate channel of the fluid director or directly into the drinksupply steam and the appropriate beverage container in the beveragecontainer compartment. It should be appreciated that for some beverages,both the carbonated and non-carbonated water will be employed to createthe correct mixture for the carbonated beverage.

[0028] In one embodiment, each water dispenser is a substantiallycylindrical ring or tube referred to herein as a water ring. The waterring defines a central opening or aperture which enables the drinksupply to flow through the water ring. The water ring includes aplurality of relatively small openings or orifices along its lower orinner circumference. When water flows into the water ring from one ofthe water valves, the water flows through the orifices, forming a sprayor other relatively even distribution of water. The drink supply outletvalve of the drink supply canister is positioned over the centralopening of the water ring to direct the drink supply into the channel ofthe fluid director or directly into the beverage container through thewater ring. This causes the drink supply and the water to mix on the flyin the desired ratios. It should be appreciated that the water ring doesnot need to be cylindrical or completely cylindrical as discussed indetail below.

[0029] The gas supplier of the beverage dispenser includes one or more,and preferably a plurality of gas supply canisters which contain CO₂gas. In one embodiment, the gas supplier includes a gas supply canisterholder adapted to hold at least one and preferably a plurality of gassupply canisters. The gas supply canister holder may be attached to ormounted in the freezer compartment door, refrigerator compartment dooror any suitable location in or connected to the refrigerator. Each gassupply canister includes a gas supply canister valve. The gas supplierincludes a gas line connected to the gas supply canister holder orframe, and adapted to direct the gas to a gas manifold which equalizesor substantially equalizes the pressurized gas provided by each gassupply canister and provides a single stream of gas. In one embodiment,the gas stream serves a dual purpose and in particular is provided topressurize the drink supply canisters and to carbonate the water in thecarbonation tank for the production of carbonated water. In anotherembodiment, the gas stream is used to carbonate the water in thecarbonation tank and an independent gas pressurizer is provided topressurize the drink supply canisters.

[0030] In one embodiment, the controller includes a computer andelectronic components and connections. The computer includes at leastone processor and one or more memory devices for storing data and atleast one actuation program, routine or module. The actuation programprovides the processor with instructions for controlling the operation(including the synchronization) of the drink supply and water supplyactuators and valves for providing the correct brix ratios for differentbeverages. It should be appreciated that the actuation program willinclude the appropriate brix ratios for the different beverages adaptedto be dispensed from the beverage dispenser of the present invention. Itshould also be appreciated that the controller or the beverage requestercan include an input mechanism which enables a user to select the typeof beverage being dispensed.

[0031] It should also be appreciated that the dispensing apparatus ofthe present invention can be adapted to communicate electronically withany computer dispensing apparatus or electronic network. In oneembodiment, the computer of the controller can electronicallycommunicate with an order processing dispensing apparatus throughcommunication channels such as existing telephone lines, cable lines,wireless communications or the Internet as described in U.S. patentapplication Ser. No. 09/589,725.

[0032] The beverage dispensing apparatus of the present inventionthereby enables users to produce and dispense carbonated andnon-carbonated beverages from their refrigerators. The dispensingapparatus provides a relatively high degree of consistent control overfluid flow rates and fluid mixing. The dispensing apparatus achievesthis level of control through the use of pressurized drink supplycanisters and computer-controlled valve activation. In addition, thedrink supply canisters and gas supply containers are constructed in sucha manner so as to facilitate their standardization, manufacture andcommercialization on a large scale basis.

[0033] It is therefore an advantage of the present invention to providea beverage dispensing apparatus.

[0034] A further advantage of the present invention is to provide abeverage dispensing apparatus which dispenses a plurality of carbonatedand non-carbonated drinks from a residential refrigerator.

[0035] Another advantage of the present invention is to provide abeverage dispensing apparatus for refrigerators which has reliable andconsistent control over the flow of drink supply and water.

[0036] Yet another advantage of the present invention is to provide abeverage dispensing apparatus for refrigerators which includespressurized drink supply canisters allowing for a relatively high degreeof control over drink flow.

[0037] Still another advantage of the present invention is to provide abeverage dispensing apparatus for refrigerators which has computercontrol over drink supply and water flow.

[0038] A further advantage of the present invention is to provide abeverage dispensing apparatus for refrigerators which is relativelyconvenient to use and maintain.

[0039] Other objects, features and advantages of the invention will beapparent from the following detailed disclosure, taken in conjunctionwith the accompanying sheets of drawings, wherein like numerals refer tolike parts, elements, components, steps and processes.

Likewise, securingmember 48 includes drink supply canister receptacles or slots 52 a, 52b, 52 c and 52 d for receiving, maintaining and securing the drinksupply canisters in the holder 56. In the embodiment of the presentinvention illustrated in FIGS. 1, 2 and 4 through 9, the drink supplycanister frame or holder 22 holds four drink supply canisters 24. Itshould be appreciated that the number of beverages provided by thebeverage dispenser of the present invention could vary and that thenumber of drink supply canisters and drink supply canister receptacleswill vary depending on the number of beverages which the manufacturerdesires the refrigerator to dispense. In the illustrated embodiment, thecanister securing member 48 includes a plurality of gas supplier valves54 a, 54 b, 54 c and 54 d which are part of the gas supplier 28 and aregenerally illustrated in FIGS. 8 and 9 and described in more detailbelow. It should be appreciated that alternative embodiments of the gassupplier and gas supplier valves are further discussed in detail below.

[0087] In this embodiment, the drink supply canister access door 40 isconnected to the securing member 48 in such a manner that: (a) thesecuring member 48 opens when the drink supply canister access door 40opens; and (b) the securing member 48 closes when the drink supplycanister access door 40 closes. When the securing member 48 and drinksupply canister access door 40 are open, as shown in FIGS. 1, 4, 5, 8and 9, a user can remove used or empty drink supply canisters and insertnew or filled drink supply canisters into the drink supply canisterholder 22. In this embodiment, the securing member 48 is directlyattached to the drink supply canister access door 40 by a suitablemechanical link 56 (fragmentarily illustrated) between the drink supplycanister access door 40 and the securing member 48. Link 56 includes twoconnecting bars 58 a and 58 b which pivotally connect (not shown) thedrink supply canister access door 40 to the securing member 48. Itshould be appreciated that the simultaneous actuation of the drinksupply canister access door 40 and securing member 48 may beaccomplished using any suitable mechanical or electromechanicalmechanism or linkage including, without limitation, electronic switches,motors or other electrical devices.

[0088] As illustrated in FIGS. 1, 2, 4 and 5, one embodiment of thepresent invention includes a drink supply canister holder 22 having avertically sliding access door lock 60 which locks the securing member48 in place and prevents the drink supply canister access door 40 fromopening when in the locked position. It should be appreciated that thepresent invention can include any suitable locking device for keepingthe drink supply canister access door closed and locked, and that thelock may be located on the interior of the refrigerator 12 for aestheticreasons. The present invention further contemplates that the lock couldalso or alternatively lock the drink supply canister holder in theclosed position. It should also be appreciated that the beveragerequesters or other control device could be used to unlock, open orprovide access to the drink supply canisters. It should further beappreciated that the lock may alternatively be electrically operatedsuch as by a solenoid which is controlled by a user activator orindicator.

[0089] In the illustrated embodiment, when the securing member 48closes, the canister receptacles 52 a, 52 b, 52 c and 52 d engage andfit over the drink supply canisters 24 to restrict their movement.Additionally, when the securing member 48 closes, the gas suppliervalves 54 a, 54 b, 54 c and 54 d also depress the gas inlet valves(discussed below) in the drink supply canisters 24 to enable CO₂ gas (oranother pressurized gas such as air) to flow into and pressurize thedrink supply canisters 24 as discussed in more detail below. It shouldfurther be appreciated that a suitable alternative apparatus or methodmay be employed to pressurize the drink supply containers as discussedbelow. For instance, the gas supplier valves may include direct gasinjectors as discussed below.

[0090] In one embodiment, the drink supply canister holder 22 and thedrink supply canisters 24 include co-acting mating members (not shown)which ensure that suitable drink supply canisters are used in connectionwith the beverage dispenser 10. The present invention contemplates thatone mating member may be disposed on each drink supply canister and theother mating member for each drink supply canister is disposed on thedrink supply canister holder 22, such as in the drink supply canistersupport 42. The mating members enable the drink supply canister holder22 to receive only predetermined drink supply canisters 24, therebyensuring that users use only appropriate drink supply canisters in thebeverage dispenser of the present invention. In one example embodiment,the canister receptacles 50 a to 50 d and/or canister receptacles 52 ato 52 d have a predetermined or predefined shape (such as an irregularshape). In such case, one or both ends of the drink supply canisters 24have co-acting or mating predetermined shapes which enable the drinksupply canisters 24 to fit into such receptacles. It should beappreciated that the present invention contemplates a suitable adapteror converter which enables a non-mating drink supply canister to matewith the canister receptacles or to otherwise be installed in thebeverage dispensing apparatus and particularly the drink supply canisterholder of the present invention. These embodiments protect the integrityof the drink supply used by the beverage dispenser. It should beappreciated that the co-acting mating members could also limit the typesof drinks dispensed from certain slots. This could be employed such thatonly certain beverages can be dispensed from certain slots.

[0091] It should also be appreciated that the controller may be adaptedto determine if a suitable drink supply canister is being used in thedrink supply canister holder using sensors, switches or other suitablemechanisms which prevent the operation with incompatible drink supplycanisters.

DRINK SUPPLY CONTAINERS

[0092] Referring now also to FIGS. 10, 11A to 11D, 12, 13, 14, 15, 16,17, 17A, 18, 19, 20 and 21, in one embodiment of the present invention,as seen specifically in FIGS. 18 to 21, the drink supply container orcanister 24 is a pressurizable, cylindrical shaped encasement which hasa cylindrical wall or body 62 having top and bottom ends, a gas inletvalve 64 and a drink supply outlet valve 66. The drink supply canister24 can be constructed of any suitable type of material, having any wallthickness which is suitable for safely retaining gas and fluidpreferably within the pressure range of one (1) pound per square inch(“PSI”) to one hundred (100) PSI. One preferred embodiment of the drinksupply canister 24 is constructed from polyethelyneterathilate (“PET”),having a wall thickness of approximately 38 G PRsform, length of 247.20and diameter of 73 mm, and adapted to hold a 24 oz. volume of drinksupply.

[0093] In one embodiment of the present invention, the technique forfilling drink supply canisters can be substantially the same as thetechnique presently used when filling soft drink cans, bottles orcontainers. Specifically, the cylindrical wall 62 and one end of thecanister can be integrally formed, filled with drink supply and thencapped by the other end of the canister which is press fit or otherwiseattached to the cylindrical wall 62.

[0094] In other embodiments of the present invention, the gas inletvalve 64 or the drink supply outlet valve 66 can be used for drinksupply filling purposes. The drink supply canister 24 can be filled withdrink supply by routing drink supply through either of these valves. Forinstance, part or all of the gas inlet valve may serve as a dual purposedevice. The initial purpose is as a filling device during the productionand packaging process at the bottling facility. The second purpose isfor facilitating the flow of CO₂ or other pressurized gas into the drinksupply canister to pressurize the canister. As discussed below, the CO₂gas or pressurized air is communicated through the inlet to providepressure to the drink supply canister to facilitate consistent drinksupply delivery at desired pressure and flow rates to the drink supplyoutlet valve 66.

[0095] In one embodiment, the gas inlet valve 64 is attached to,connected to or otherwise suitably formed in one surface and in oneembodiment the top surface of the drink supply canister 24. Oneembodiment of the gas inlet valve 64 is a spring activated valve whichis predisposed to be normally closed to prevent the flow of gas into orout of the drink supply canister 24. When the gas inlet valve 64 isdepressed or actuated, gas flows through the gas inlet valve 64 into thedrink supply canister 24. The gas inlet valve 64 illustrated in FIGS.18, 20 and 21 includes a spring or biasing member 68 and a sealingmember 70. As further described below, in this embodiment, the closingof the drink supply canister securing member 48 causes gas inlet valve64 to be depressed as specifically illustrated in FIGS. 20 and 21. Itshould be appreciated that any suitable gas inlet valve may be employedin the drink supply canister of the present invention as furtherdiscussed below. It should also be appreciated that the gas inlet valvemay be removably connected to the body of the drink supply canister.

[0096] In one embodiment, the drink supply outlet valve 66 is attachedto, connected to or otherwise suitably formed in one surface andpreferably the bottom surface of the drink supply canister 24 asillustrated in FIGS. 19, 20 and 21. One embodiment of the drink outletvalve 66 includes a sealing member 74 which is positioned in the bottomwall or end 72 of the drink supply canister such that the sealing member74 can be tilted or displaced horizontally. In this embodiment, a spout76 is attached to the bottom wall 72 and surrounds the sealing member74. Spout 76 is movably attached to the bottom wall 72 with suitableflexible snap fittings. Spout 76 is preferably cylindrical or conical inshape having opposing open ends. In this embodiment, the drink supplyoutlet valve 66 maintains a seal on the inside of the body of the drinksupply canister 24 when the drink supply canister 24 is pressurized. Inthis embodiment, the drink supply canisters 24 are filled with drinksupply and a sufficient volume of CO₂ gas or other pressurized gas orair to provide an internal pressure sufficient to enable the drinksupply outlet valve 66 to maintain such a seal during shipment and priorto use. The pressure and temperature conditions suitable for the drinksupply outlet valve to maintain such seal will vary depending on thesize and shape of the drink supply canister. In one preferredembodiment, the pressure maintained in the drink supply canister isapproximately ten (10) PSI during shipment and approximately fifteen(15) PSI when inserted into the drink supply canister holder to maintaina consistent flow of beverage through the drink supply outlet valve. Inthis embodiment, when the spout 76 is displaced in a horizontal orsubstantially horizontal fashion as described below, the sealing member74 unseats, and drink supply outlet valve 72 opens and enables thepressurized drink supply to flow through the spout 76. It should beappreciated that other suitable actuatable drink supply outlet valvesmay be employed in the drink supply canisters of the present inventionas further discussed below. It should also be appreciated that the drinksupply outlet valve can be removably attached to the body of the drinksupply canister.

[0097] In this embodiment of the drink outlet valve 66, one or moredrink supply outlet valve actuators 78 are suitably mounted to thebottom of or adjacent to the drink canister support 42 to co-act withthe drink supply outlet valves. The drink supply outlet valve actuators78 can include any suitable mechanical or electromechanical actuatingdevice, such as a solenoid 80 connected to an extension piston, pin orrod or other valve engager or engagement member 82. In the illustratedembodiment, when a user activates a beverage requester 36, thecontroller 38 (described below) causes the appropriate drink supplyoutlet valve actuator 78 to engage and displace spout 76 for apredetermined period of time, which in turn causes the drink supply toflow from the drink supply canister 24 as specifically illustrated inFIGS. 7, 11B and 17 and discussed below. After the predetermined timeperiod elapses, the drink supply outlet valve actuator 78 disengagesspout 76, stopping the flow of the drink supply from the drink supplycanister 24.

FLUID DIRECTOR

[0098] One embodiment of the beverage dispenser of the presentinvention, as seen in FIG. 2, includes a fluid director such as thefluid director 34 of the beverage dispenser 10. The fluid director 34 isadapted to simultaneously receive the flow of drink supply from thedrink supply canisters 24 and also carbonated or non-carbonated waterfrom the water supplier 26. The fluid director 34 is made from asuitable plastic or polymer such as food grade plastic materials, suchas by injection molding, although it could be made from other suitablematerials and formed in suitable other manners. The fluid director 34includes at least one, and in the embodiment illustrated in FIGS. 10,11A, 11B, 12, 13, 14, 15 and 16 a plurality of walls 92, which defineand separate the channels 84. The separate channels 84 in the fluiddirector 34 separate the different drink supplies from one another toprevent cross-contamination which occurs when different types ofbeverages mix. Preferably, at any one time, when a user operates thedispensing apparatus 10, only one channel 84 of the fluid director 34 isused. In operation, the drink supply mixes with the carbonated ornon-carbonated water in one of the channels 84 in the fluid director 34,and the fluid director 34 directs the mixture into the beveragecontainer or collector 32 in the beverage container compartment 30 (seeFIGS. 1, 4, 5, 6 and 7). The fluid director 34 illustrated in FIGS. 1,2, 3, 4, 5, 6, 7, 10, 11A, 11B, 12, 13, 14, 15 and 16 includes fourchambers or channels 84. In one embodiment, each channel 84 acts as aVenturi tube or passageway which includes a channel entrance 86, throat88 and a channel exit 90, as specifically illustrated in FIG. 16. In oneembodiment, the area of the channel entrance 86 is generally larger thanthe area of the channel exit 90. The channels are sufficiently sized toenable the drink supply and the water to sufficiently mix to form thebeverage. The fluid director 34 is thus constructed with predetermined,dimensions and a predetermined shape to enable the typical beveragesupply to mix sufficiently with the water and to facilitate control ofthe beverage brix ratios by suitably adjusting the pressure and flowrate of drink supply and water. It should be appreciated that the fluiddirector could alternatively include a plurality of separate ornon-integral chambers, funnels, passageways or fluid communication linesas illustrated in FIG. 28 and further discussed below.

[0099] In one embodiment, the fluid director 34 is adapted to be removedfrom the refrigerator primarily to enable a user to clean the fluiddirector. In one embodiment of the present invention, the beveragedispenser 10 includes a fluid director access door 94 pivotally orotherwise movably connected to the exterior of freezer compartment dooras generally illustrated in FIGS. 1, 4, 5, 6 and 7. When the fluiddirector access door 94 is opened, a user can remove the fluid director34 as illustrated in FIG. 5. The fluid director can be cleaned by handor automatically, such as in a household dishwasher. The fluid director34 is secured within the refrigerator through the use of one or moreslots (not shown). Alternatively, the beverage dispenser may include oneor more locks for securing the fluid director and fluid director accessdoor. In one alternative embodiment, the fluid director includesalignment or mating features such as an edge with a grooved surfacewhich is adapted to line up with grooved slots in the refrigerator tocreate a secure snap fit connection. It should be appreciated that thefluid director access door may be on the interior of the freezercompartment. It should further be appreciated that the beveragedispenser including the fluid director may also be in the refrigeratordoor.

[0100] The water supplier 26 provides carbonated and non-carbonatedwater for producing the beverages. In one embodiment, part of the watersupplier is located in the lower portion of the refrigerator 12 asillustrated in FIG. 2. In one embodiment, as schematically illustratedin FIG. 3, the water supplier 26 generally includes a water filter 96, awater pump 98, a two-way water valve 100, a water pressure regulator102, a suitable water storage or holding tank 104, a carbonation tank106, a cold transfer device 108, a carbonated fluid communication waterline or conduit 110 and a non-carbonated fluid communication or waterline or conduit 112. The water supplier 26 is preferably connected to adrinkable water source, such as a conventional cold water sourceavailable in residential kitchens.

[0101] In operation, the water passes through the water filter 96 intothe water pump 98. The water filter 96 preferably removes chlorine andmoderate particles from the water to enhance and establish a consistentflavor of the water which is important for maintaining consistency inthe dispensed beverages. It should be appreciated that other suitablewater filter, filtration or purification systems may be used inconjunction with the present invention to provide a consistent taste tothe beverages. The water pump 98 may be any suitable water pump such asa commercially available 115V AC pump which preferably regulates thewater pressure to approximately ninety-five (95) pounds PSI. The waterpump 98 pumps the water to the two-way water valve 100. The two-waywater valve 100 directs the water to the holding tank 104 and thecarbonation tank 106. The water pressure regulator 102 preferablydecreases the water pressure in the holding tank 104 to a manageablewater pressure of approximately fifty (50) PSI. The water pressureregulator may be any suitable regulator such as a commercially available50 PSI regulator. It should be appreciated that the water pump may beconnected to the water lines by suitable quick disconnect connections asillustrated in FIG. 24D discussed below.

[0102] The holding tank 104 preferably stores a sufficient supply ofnon-carbonated water. The refrigerator 12 maintains this reserve watersupply at a relatively low temperature and preferably about forty-five(45) degrees Fahrenheit or less (but not less than thirty-eight (38)degrees Fahrenheit). In this embodiment, the water supply from theholding tank 104 is used if a user requests the dispensing apparatus todispense non-carbonated water alone or if the dispensing apparatus 10requires substantial amounts of non-carbonated water.

[0103] As illustrated in FIG. 3, the carbonation tank 106 is, in oneembodiment, connected to the gas supplier 28. The carbonation tank 106uses CO₂ gas obtained from the gas supplier 28 to carbonate the water.The carbonation tank 106 can include any suitable tank or encasementadapted to withstand the pressure of the CO₂ gas provided by the gassupplier 28 and the carbonated water. The carbonation tank 106preferably includes a conventional safety valve (not shown) whichexhausts the necessary amount of pressure in the carbonation tank 106when the pressure inside carbonation tank 106 exceeds a predeterminedpressure. The safety valve closes when the pressure inside thecarbonation tank 106 is below or reaches a predetermined pressure. Thecarbonation tank 106 also preferably includes a conventional back flowpreventer (not shown) which prevents the carbonated water from flowingbackward to the water source.

[0104] The non-carbonated water from the holding tank 104 and thecarbonated water from the carbonation tank 106 preferably pass through acold transfer device 108 (or alternatively receive chilled water via therefrigerator reserve water supply (not shown), preferably chilled atthirty-eight (38) to forty-five (45) degrees Fahrenheit in separatefluid communication lines or conduits). The cold transfer device 108decreases the temperature of the water so that the resulting mixture ofthe drink supply and carbonated water (i.e., the beverage) maintains arelatively high level of carbonation for optimal drinking enjoyment. Inone embodiment, the cold transfer device 108 is a conventional devicewhich includes one or more tubes or lines (not shown) which are routedthrough a conventional cooling device (not shown). Preferably, the tubesare constructed of aluminum or steel. The cold transfer device 108 maybe constructed of any suitable size or shape, such as eight (8) inchesby twelve (12) inches by two (2) inches.

In one embodiment, the water supplier 26 includes aplurality of separate or individual carbonated water valves 114 andnon-carbonated water valves 116. The carbonated water valves 114 areconnected to the carbonated water line 110, and the non-carbonated watervalves 116 are connected to the non-carbonated water line 112. In onealternative embodiment, which is illustrated in FIGS. 10, 11A, 11B, 12and 13, a suitable water valve actuator 118 is connected to or mountedadjacent to each carbonated water valve 114 and each non-carbonatedwater valve 116. In one embodiment, the water valve actuator 118 includea conventional mechanical actuator (not shown) coupled to a conventionalelectrical activator (not shown).

[0106] In this embodiment, one carbonated water line and associatedwater valve and one non-carbonated water line and associated water valveis associated with each drink supply canister held by the drink supplycanister holder. It should be appreciated that, at any one time onlycarbonated water or only non-carbonated water may be distributed to oneor more designated slots for drink supply canisters because suchcontainers are designated to produce only carbonated drinks ornon-carbonated drinks, respectively.

[0107] When a user activates a beverage requester 36, the controller 38sends a signal to the appropriate water valve actuator 118 to cause theappropriate carbonated water valve 114 or the appropriate non-carbonatedwater valve 116 associated with the desired drink supply canister toopen. The water valve actuator 118 keeps the valve open for apredetermined time period, preferably simultaneous with the opening ofthe drink supply outlet valve in the drink supply canister as describedherein. After such time period elapses, the actuator 118 causes orallows the appropriate valve 114 or 116 to close. As mentioned above, itshould be appreciated that the beverage dispenser of the presentinvention could be adapted to open the drink supply outlet valve and thecarbonated water valve or the non-carbonated water valve beginningsimultaneously at the time the user activates the beverage requester andcontinuing until the user releases or deactivates the beveragedispenser. This embodiment enables the user to determine the amount ofbeverage, dispensed instead of predetermined or fixed amounts beingdispensed.

[0108] In one alternative embodiment illustrated in FIG. 14, thecarbonated water line 110 is connected to a single multi-way carbonatedwater valve 120, and the non-carbonated water line 112 is connected to asingle multi-way non-carbonated water valve 122. When a user activates abeverage requester 36, the actuator 118 causes one of the multi-wayvalves to open and direct water to one of a plurality of channels 84 ofthe fluid director for a predetermined time period. It should beappreciated that any suitable device may alternatively be employed toappropriately direct the water and that the multiway valves may beemployed in conjunction with the embodiments described herein which donot include a fluid director.

The orifices are preferably locatedon the inner diameter of the center of the water ring 124 preferably ata seventy (70) degree angle from the horizontal plane defined by thewater ring. When water flows into the water ring from the water line 110or 112, the water is directed through the orifices 127, forming arelatively evenly distributed circular spray of water. This circularspray completely surrounds the stream of drink supply which flowsthrough the central aperture 125. The drink supply stream which in oneembodiment is substantially cylindrical in shape, including asubstantially cylindrical stream wall. The spray of the water streamsfrom the water ring strikes and interacts with or penetrates this streamwall at a plurality of positions along the circumference of the drinksupply stream wall. In this embodiment, there are a plurality of suchpositions which are approximately uniformly spaced about the entirecircumference of the drink supply stream wall. In one alternativeembodiment, there are at least four of such positions separated from oneanother by approximately ninety (90) degrees to provide sufficientpenetration and mixture. It should be appreciated that other positionsor arrangements may be employed in accordance with the presentinvention.

[0112] In a further embodiment, as discussed below in relation to FIG.29, the water ring 124 a includes a plurality of water injectors 125 afor directing the carbonated or non-carbonated water into the drinksupply stream. The water injectors 125 a determine the approximatepositions along the drink supply stream wall which will receive a flowor injection of water. The water injectors 125 a also determine orcontrol the angle at which the water will flow out of the water ring 124a. The specific water pressure, canister pressure, shape and dimensionof the water ring and water injectors and the angular orientation of thewater injectors all affect the water-drink supply mixing process. Thesefactors or variables can be determined so as to establish a relativelyhigh quality and reliable mixing process.

[0113] As specifically illustrated in FIGS. 11A and 11B, the drinksupply outlet valve 66 of the drink supply canister 24 is positionedabove the central aperture of the water ring 124 to direct the drinksupply into the channel 84 through the central aperture 125 in the waterring 124. In an alternative embodiment illustrated in FIG. 29, the drinksupply canister is positioned offset from the water ring 124 a (see FIG.29). When the drink supply outlet valve actuator 78 engages the drinksupply outlet valve 66, the drink supply is directed through the centralaperture of the water ring (as illustrated in phantom in FIG. 29).

[0114] In one alternative embodiment, the carbonated water lines andvalves are connected to a single water dispenser (not shown). The waterdispenser includes internal walls which form separate sections for eachcarbonated water valve. The non-carbonated water line and valves arealso connected to a single water dispenser (not shown). This waterdispenser includes internal walls which form separate sections for eachnon-carbonated water valve. In a further alternative embodiment, aplurality of water rings (not shown) are connected or joined, forming asingle member which distributes water in the same manner as if the waterrings were separated. In a further alternative embodiment, the waterdispenser includes opposing water injectors connected to the valveswhich direct carbonated and non-carbonated water in the appropriatedirection to mix with the drink supply from the drink supply canisters.

[0115] It should be appreciated that the water dispenser or water tubeof the present invention does not have to be circular, cylindrical orsubstantially cylindrical. The water tube of the present invention maybe any suitable shape. For instance, the water tube 124 c may not becompletely circular as illustrated in FIG. 11C. The water tube 124 d mayalso, for instance, be semi-circular as illustrated in FIG. 11D.Preferably, the water tube does not include sharp turns which tend tocause turbulence in the water tube and unequal dispensing of the water.

The watersupplier 26 provides a supply of water (preferably including bothcarbonated and non-carbonated water), available for delivery to thefluid director 34 as indicated by block 168. The gas supplier 28 routesgas to the carbonation tank 106 of the water supplier 26 and preferablyroutes gas to the drink supply canisters containers 24, as indicated byblock 170.

[0149] When a user provides an input, for example, by pushing one of thebeverage requestors 36, the controller sends a signal to the appropriatevalve actuators for causing the appropriate valves to open forpredetermined periods of time, causing the drink supply and water toflow into at least one channel 84 of the fluid director 34, as indicatedby block 172. The drink supply-water mixture flows through channel 84and into a beverage container 32, as indicated by block 174. A user canthen drink and enjoy the desired beverage, as indicated by block 176. Itshould be appreciated that the same general process will apply to theembodiments without the fluid director, wherein the drink supply andcarbonated or non-carbonated water are mixed on the fly and directedinto the beverage container.

[0150] It should also be appreciated that the beverage requestors couldalternatively enable the user to control the volume of beveragedispensed by the amount of time the user activates the beveragedispenser (such by pushing a mechanical beverage requester button) or byinputting a volume amount (such as selecting one of a four (4) ouncebeverage container indicator, eight (8) ounce beverage containerindicator, twenty (20) ounce beverage container indicator, ortwenty-four (24) ounce beverage container indicator on a beveragerequester in the form of an input screen or touch screen.

ALTERNATIVE EMBODIMENT WITHOUT FLUID DIRECTOR

[0151] As mentioned above and as generally illustrated in FIGS. 24B, 24Cand 29, one preferred alternative embodiment of the beverage dispenserof the present invention, generally indicated by numeral 10 a, does notemploy a fluid director. The beverage dispenser 10 a of this embodimentdirectly dispenses the drink supply and the carbonated or non-carbonatedwater into the beverage containers or collectors 32. The beveragedispenser 10 a is adapted to be mounted in a housing and preferably in arefrigerator as described above with respect to beverage dispenser 10.

[0152] Generally, the beverage dispenser or beverage dispensingapparatus 10 a of this embodiment of the present invention includes: (a)a drink supplier including a drink supply canister holder or frame 22 afor holding or maintaining at least one and preferably a plurality ofdrink supply canisters 24 and drink supply valve actuators 78 forcausing the drink supply to be selectively released from the drinksupply canisters 24; (b) a water supplier 26 for selectively supplyingcarbonated water and non-carbonated water for mixing or making thebeverages; (c) a gas supplier 28 a for supplying CO₂ gas to carbonatethe carbonated water provided by the water supplier 26, and forsupplying CO₂ gas or other pressurized air for pressurizing the drinksupply canisters 24; (d) a beverage container compartment 30 for holdingone or more beverage collectors or containers 32 (such as a glass, cupor pitcher); (e) a controller (not shown) for controlling and trackingthe dispensing of drink supply and carbonated or non-carbonated water;and (f) one or more suitable beverage requesters (not shown). In theembodiment illustrated in FIGS. 24B and 24C, the beverage requesters areconventional levers 37 a, 37 b, 37 c and 37 d mounted in the beveragecontainer compartment 30 and are preferably in electronic communicationwith the controller (not shown). It should be appreciated that thebeverage requesters could alternatively be directly in communicationwith the valve actuators. Also, in other embodiments the beveragerequesters can be levers which are preferably spring-activated. When auser pushes a lever, the beverage dispenser dispenses beverage into theuser's beverage container.

[0153] Generally, in operation, after the user installs the drink supplycanisters 24, the gas inlet valve 64 associated with each drink supplycanister 24 causes the CO₂ gas to flow from the gas supplier 28 a intothe drink supply canisters 24. This pressurizes the drink supplycanisters 24. When a user desires to obtain a beverage, the user makesthe user's request through the appropriate beverage requester 37 a, 37b, 37 c or 37 d which is connected to or in communication with thecontroller. Upon receiving a beverage dispense signal, the controllercauses the drink supply outlet valve actuator (not shown) to cause thedrink supply outlet valve (not shown) associated with the appropriatedrink supply canister 24 to open to dispense the appropriate amount ofdrink supply from that drink supply canister 24. This drink supplystream is directed downward into the beverage container 32.Simultaneously, the controller causes the water supplier 26 to directthe appropriate amount of carbonated or non-carbonated water through theappropriate water dispenser into the stream of the drink supply and intothe same beverage container 32 as specifically illustrated in phantom inFIG. 29. The drink supply stream and the carbonated or non-carbonatedwater stream mix on the fly while directed into the beverage container32. In one preferred embodiment, the beverage dispenser of the presentinvention includes a water dispenser or water ring associated with eachcanister and associated carbonated and non-carbonated water linesconnected to each water ring as discussed above.

[0154] In one embodiment, as seen in FIG. 29, the beverage collector 32is positioned with respect to the drink supply outlet valve 66 and waterdispenser 124 a in such a manner that the water streams 131 frominjectors 125 a contact the drink supply stream 129 at a location insidethe collector 32. The collision of the fluid streams occurring below thetop of the collector 32 minimizing the spilling, loss and splashing offluids. In this embodiment, it should be appreciated that the waterstreams 131 interact and mix with the drink supply stream 129,preferably in mid-air as well as within the collector 32 as the beveragerises to the top of the collector 32.
